Title: Decanting device for supernatant liquid - has cup with light for determining sediment level
Inventor: TLUSTY HANS-JUERGEN
IPC: B01D21/00
Filed: 1972-11-15
Abstract: The appts. is esp. for uses with deeply coloured solns. An inverted 'U' tube which is adjustable in height is used for drawing off liquid after the sediment has setled in a settling tank. The bottom of the tube is surrounded by a cup with a cone valve in the bottom. The cup bears a light shining into a fibre optics light guide. When settling has taken place, the cone valve is closed and the cup is lowered unti lthe light ceases to shine through the light guide indicating that the cup is now resting in the sediment. The supernatant liquid is then drawn off. After the decanting operation is complete and the sediment is removed the appts. is flushed out. At this point the cone valve is opened to allow any sediment in the cup to fall out.

Title: Electron beam marking of workpieces - by beam scanning and row stepper motion controlled by process computer
Inventor: SCHMITT ADOLF DR-ING
IPC: B23K26/00
Filed: 1973-07-17
Abstract: Alphanumeric symbols are marked for identification purposes on tools or wearing surfaces of structural elements by an electron beam which is guided across the workpiece surface by a programmable process computer. The electron beam pulses produce marks by local material evaporation in a raster pattern which can have any desired magnification factor. The system is not limited to unhardened metal surfaces like the stamping operation. It produces durable marks in hardened surfaces without causing any a symmetrical surface stresses. It can be applied as the last operation so that the marking depth is not reduced by grinding etc.

Title: Easy switch-off thyristor of integrated transistors - has partial vertical transistor of high current amplification and lateral low-amplifying one
Inventor: AULBACH RUDOLF DIPL-PHYS
IPC: H01L29/74
Filed: 1973-07-17
Abstract: The two transistors form an integrated semiconductor chip with a thin, high-resistance film, with a low-resistance region of identical conductivity underneath. This region provides low flow resistance of the thyristor, with a low life of minority charge carriers. One part of the region, extending laterally over the vertical transistor emitter zone is of increased width and is provided with a switch-off contact. This wider part and the contact extend along the emitter edge of the vertical transistor and also across this direction in a manner sufficient for derivation of a high switching-off current flow across the base contact from the base current flowing internally in the semiconductor body towards the vertical transistor.

Title: Continuous filament depositing system - uses a rotating air jet to swirl filaments in a spiral on to carrier conveyor
Inventor: MENTE KURT
IPC: D04H3/03
Filed: 1974-02-20
Abstract: Continuous synthetic filaments are deposited into a tangled blanket layer, using a rotary unit to spin the filaments in their airstream round a central axis to give a spiral overlapping deposit on the conveyor. The system gives an even and homogenous layer of filaments, with a delivery unit which can be adjusted easily. The filaments are delivered through an air jet unit to give a band width which, when rotated, gives a circular deposit across the width of the carrier surface on which the filaments are to be deposited.

Title: Cct. adjusting phase position of AC voltage with control voltage - extracts co-ordinated complex colour carrier signal
Inventor: SCHUSTER WILHELM DIPL ING
IPC: H04N9/45
Filed: 1974-02-25
Abstract: The circuitry, for adjusting the phase of an AC voltage with a controlling voltage through a range of 0 deg. to 36 deg. is for use in e.g. colour TV studios where remote-controlled adjustment of a colour carrier may be desired. The circuit receives an AC voltage of given phase through a terminal and feeds it to a frequency divider and a phase discriminator. The AC voltage from the divider is fed to a function generator which forms a saw-toothed voltage, which is input to a threshold switch. The voltage level above which the threshold switch operates is continuously adjustable through a terminal voltage. The signal from the threshold switch is transformed by an impulse former into an impulse which is fed into a frequency doubler whose output is an AC voltage having the same frequency as the input, but with a different phase.

Patent DE-2413573-A1 (DE)
Title: Resistance measuring instrument for HF apparatus - uses EMF proportional voltage and does not need EMF kept at constant level
Inventor: HEIDEN KURT
IPC: G01R27/02
Filed: 1974-03-21
Abstract: The instrument is intended primarily for measuring impedances and reflection factors in h.f. apparatus by determining the difference between an unknown resistance and a known resistance in a bridge circuit. The need to keep the e.m.f. constant is eliminated by measuring the voltage dependent on the e.m.f. and the unknown resistance and the voltage proportional to the e.m.f. and independent of the unknown resistance. The reflection factor may be determined directly by obtaining the quotient of the two voltages.

Title: Equal load distribution in parallel rectified supplies - is achieved by connecting the secondary windings of the supply transformers serially
Inventor: POREP EBERHARD DIPL ING
IPC: H02M7/48
Filed: 1974-04-17
Abstract: A number of direct voltage supply units are connected to supply one load in parallel, but with simple guaranteed equal load sharing is presented. Each supply consists of a transformer of which the secondary is connected to the mains and the primary is used to rectify and to supply the required direct voltage and current. Each primary winding is connected via a switch to a rectifying unit and the outputs of many of these may be connected in parallel. The switch is a changeover single pole switch, which in the 'off' position shorts out the primary winding. Each switch is also gauged to a further pair of contacts which in the 'off' position shorts out the secondary winding. All the secondary windings are connected serially. These arrangements guarantee that all the primary currents are equal and so that the load sharing is equitable. When a particular supply is to be disconnected, its switch is put in the 'off' position when the rectifier is disconnected and the windings shorted out. The switch may be of a semiconductor type for remote control.
